Hi,

the cases consists of heatsink profiles from http://www.fischerelektronik.de and milled front plates from www.schaeffer-apparatebau.de / www.frontpanelexpress.com.

Indeed a sharp looking amp.
Did you ordered those alu profiles directly from Fischer Elektronik or through a retailer?

Hi GeWa,

I have ordered the alu profiles in meter pieces directly from Fischer. They were expensive, probably you can get them cheaper from a retailer like Schuro.

Jimbo and 1543-

Both beautiful.

Any chance to see the insides? To me that is where the real art happens.

But they are visually impressive also. 😉

Hi Troy,

here you can see the inside of the amp

An externally hosted image should be here but it was not working when we last tested it.

You never said if you fixed the motorboating?

Motorboating? What?

Here's a pic of a TDA2009 amp I made:

I recently took out the PCB and I am trying at make a nicer case for it that has more room and that i can have nicer sound quality.

Motorboating? What?

A non-technical term for low frequency oscillation usually caused by uneven power supply filtering.

Arne (1543), can you tell more about prices - especially this front panel. Your enclosure look great!

 

[1543]

Hi veteran,

the frontplates were 28,70€ each and the heatsink profiles costs around 50€ for each amp.

CMoy Headphone Amplifier

Attached is my latest project. A CMoy headphone amplifier. It uses the OPA2132PA opamp.

On the success of this project, I want to try a desktop unit with volume control, bigger input caps, regulated power supply and bypass caps on the chip.

There are a couple more pictures and details at my website.

Overall, the CMoy performs well and it increases listening pleasure with a good set of headphones.

Cheers,
Gio.

Looks better covered up...

Nice looking design, if you took those two aluminum profiles, stacked them end to end, and offset them by 12.25° it would be the profile of the patronis towers in singapore. wow, definately not an architecture student here~

Can't wait to post my GC amp, ordering the PCBs tommorrow and doing my parts-sourcing this weekend, I finally get to use this pair of 22,000uF caps I've had sitting on my bech for 3 years YAY

-cheers,
Daniel

Rebuilt LM4780

Well after cooking the first set of chips my first Lm4780 is up and running.
This has been a long process(1 year) since I first ordered the chips from National.
This one sounds way more dynamic if i could use that term without getting too airy fairy. I think this has to do with the power supply, as this one was built with a dual mono and it is a parallel design. I used two 300va trannies and four bridge rectifiers.
I think this made all the difference, more power😉
Anyway its not perfect, as there are a few things I'm still sorting(tweaking) as you do..............
